4805.92.20.00 - Pressboard

This HTS classification covers pressboard that is not coated and is presented in rolls or sheets. The material has undergone only basic processing as defined by note 3 to Chapter 48, meaning it is suitable for its intended use without further significant modification. Pressboard, in this context, refers to a dense, stiff paperboard formed under pressure, typically used for applications requiring rigidity and durability, such as covers for books, binders, or as backing material.

Within the broader category of "Other uncoated paper and paperboard," this specific code, 4805.92.20.00, is further refined by weight. It is distinct from sibling categories by its defined weight range of exceeding 150 g/m² but not surpassing 225 g/m². Other classifications at this level might cover pressboard with different weight characteristics or perhaps other forms of uncoated paper and paperboard not specifically defined as pressboard. The sibling category, 4805.92.40, also falls under "Other" and would likely encompass other paper or paperboard products within the same weight bracket but not fitting the specific definition of pressboard or other more precisely defined subcategories.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification at this level relies on the accurate identification of the material as pressboard and its adherence to the specified weight parameters (greater than 150 g/m² and less than 225 g/m²). Importers and exporters should ensure that the product's characteristics precisely match these criteria to ensure correct customs declaration and avoid classification disputes.
